Method for breeding high-quality penaeus vannamei boone parent shrimps

Abstract

The invention belongs to the technical field of aquiculture and discloses a method for breeding high-quality penaeus vannamei boone parent shrimps. The method comprises the following steps in turn: catching penaeus vannamei boone raw parent shrimps from natural sea areas; classifying and throwing the raw parent shrimps caught in different natural sea areas into different sealed breeding domestication pools; screening virus-free healthy raw parent shrimps; strengthening the raw parent shrimps; breeding parent shrimp seedlings; breeding the parent shrimps; and strengthening the parent shrimps at a later stage. The penaeus vannamei boone parent shrimps bred by the breeding method have the advantages that: (1) the shrimps do not have specific viruses, namely white spot syndrome virus, Taura syndrome virus, hypodermal and hematopoietic necrosis virus and other viruses with severe harm to the growth of the shrimps; and (2) the growth speed and disease resistance are high, the raw shrimp germ line is good, and the produced parent shrimps grow faster than general shrimp seedlings in a stocking period, have higher disease resistance, high feed conversion ratio and high yield and survival rate.

Description

technical field [0001] The invention belongs to the aquaculture technology, and in particular relates to a breeding method for high-quality broodstock of Penaeus vannamei. Background technique [0002] Since the 1980s, the shrimp aquaculture industry in the coastal countries of the world has developed vigorously. Penaeus vannamei has become one of the three types of shrimp with the highest aquaculture output in the world today due to its delicious meat, strong adaptability, rapid growth and strong disease resistance. With the large-scale development of the shrimp farming industry, the breeding area and farming intensity are increasing, the ecological environment of farming is deteriorating, and diseases are becoming more and more prominent, especially viral diseases. Since Couch et al. discovered the first shrimp virus (BP) in 1974, the number of shrimp viruses reported in the world has reached 7 families and 19 species, including: inclusion body baculovirus, non-inclusion ...

AI Technical Summary

Problems solved by technology

[0004] High-quality broodstock must meet the following basic conditions: (1) No specific virus: no WSSV (white spot virus), TSV (Taura virus), IHHNV (subcutaneous and hematopoietic tissue necrosis virus) and other viruses that seriously damage the growth of shrimp; ( 2) Rapid growth and strong disease resistance: The species of shrimp with good species grow faster than ordinary shrimp during the stocking period, and have stronger disease resistance, enhance the rate of feed replacement and increase the survival rate of harvest; (3) reach Mature standard and young and strong: Mature species of shrimp are considered to have grown for more than ten months, and the production period has not exceeded five months. If expired species of shrimp continue to be produced, the quality will decline and it will be unfavorable for breeding
